1 Colic is likely to start around age 2 weeks if your infant is full-term (or later if premature). 2  It almost always goes away on its own by 3 or 4 months. 3  Your baby's sex and birth order, and whether you breast- or bottle-feed, donât affect it.  Kids who had colic as babies are no different from those who didnât.
The crying is usually worst when babies are around 6 to 8 weeks of age, and it goes away on its own between 8 and 14 weeks of age. Doctors are not sure what causes colic. It may be related to gas in the belly, an immature nervous system, or your baby's temperament. Abdominal cramps from overfeeding or milk intolerance.
